Do I need an SAFC?

[camas90gsx]

I have a 90 gsx with an EVO 3 16G, Evo 3 o2 housing (heavily ported), Evo 3 manifold(heavily ported), Walboro 255 (installed, not rewired), Perrin MBC, 2G maf,3in turbo back exhaust no cat and 550 injectors that will be here in the next few days, 650cc fic injectors,that are here and an safc that isnt installed yet. Right now I have a 1g maf attached to the car, with lower honeycomb removed and k&n filter. The reason I dont have the 2g maf installed yet is because I have a 2g hard pipe with a k&n filter kit attached that is too long, because im still running my smic (punishment fmic is on its way here and installed in the next week). So basically besides the fmic, what should I do with this set up? I dont want to put in the 550 injectors and then have to turn around and put in 650s as a result of running to lean, because im super busy with work, and am trying to do this myself as much as possible. Which injectors would be best for this setup? Also, if I do need to install the safc, how do I go about doing that, and tuning it. I have no knowledge of safc at all, so any help or advice would be great. Thanks

Yes. Install it or buy another tuning solution.
You also should be using a wideband to tune with.
Here are a few links I found after searching for less than 5 minutes.

SAFC Install on a 1G

How to tune it.

Okay, I will install the safc, I am also going to be putting on a fmic and 2g maf this week. I would like to be able to turn my boost up to 18-20 after I install those, but which injectors do you think would be better, the 550's or the 650's?

Before you get injectors get your wideband, 650s are good.

Ok, i looked at the link on how to tune an safc and dont understand most of it.I guess i probably shouldnt even install the safc if i cant understand how to tune with it.Probably my best option at this point is to install the 550's not the 650's along with my 2g maf and other mods and hope i dont run too rich and if i do then go back to 450's and 1g maf and call it good.Dont y'all think? idk?

Or another thought,could i get my ecu socketed then get a progammed chip with injector size and maf compensation.Or send off my ecu to get reprogrammed for what i want it to do?Sorry i just dont know if i will be able to tune with the safc,and the last thing i wanna do is install it and then be stumped on what to do next.Any help would be MUCH appreciated.
